Do not group ordinal numbers, years, page numbers, military unit designations, instrument model numbers, or standard numbers.

For mean ± standard deviation, present as: "(19.8±3.7) mg" or "(30.6±5.1)%". Use a wave dash "~" to indicate numerical ranges (e.g., 2%~8%). For measurements with units, write as: "4 cm × 3 cm × 5 cm" (not "4×3×5 cm").
